# Volume Differential

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Volume differential, abbreviated as $$\Delta V$$, is the difference between an expanded or reduced volume of a liquid.

## Formulas that use Volume Differential

 $$\large{ \Delta V = V_f - V_i }$$ $$\large{ V_c = \frac {p \; V_i}{ K} }$$

### Where:

$$\large{ \Delta V }$$ = volume differential

$$\large{ K }$$ = bulk modulus

$$\large{ V_c }$$ = change in volume (volume differential)

$$\large{ V_f }$$ = final volume

$$\large{ V_i }$$ = initial volume

$$\large{ p }$$ = pressure
